Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Because the MCU function testing method in the prior art has a high degree of dependence on the SOC function, and usually is a black box test, and needs to be verified manually, there are disadvantages of low testing efficiency, high testing cost, low testing coverage of the MCU function (i.e. the case where boundary values, abnormal scenes, etc. cannot be verified), delayed problem exposure, high problem analysis cost (the analysis sequence is usually an application development stage, an SOC function development stage, and an MCU function development stage, i.e. it is necessary to analyze whether the MCU function is generated at last), and the like. Therefore, the embodiment of the invention provides a method for testing the functions of the micro control unit, which can be used for testing the functions of the micro control unit matched with the SOC function in the application process.
Fig. 1 is a schematic flowchart of a MCU function testing method provided in an embodiment of the present invention, and as shown in fig. 1, the method includes:
s1, establishing communication connection with a micro control unit based on communication service with an auxiliary test unit, executing a test case script corresponding to a function to be tested of the micro control unit, and calling a function module script corresponding to the function to be tested;
s2, sending test data to the micro control unit based on the function module script so that the micro control unit executes the function to be tested based on the test data;
s3, receiving an execution result fed back by the micro control unit;
the communication protocol between the auxiliary test unit and the micro control unit is a target communication protocol between the micro control unit and a system-on-chip.
Specifically, in the MCU function testing method provided in the embodiment of the present invention, the main execution body is an MCU function testing device, the device may be configured in a computer, and the local computer may be a local computer or a cloud computer, and the local computer may be a computer, a tablet, or the like, which is not specifically limited in the embodiment of the present invention.
The MCU function test device can establish communication service with an auxiliary test unit, and the auxiliary test unit can be a pipeline service module of an MCU in an SOC, that is, an MCUPIPE service module, or a third-party device, which is not specifically limited in the embodiments of the present invention.
The auxiliary test unit is used as an information transmission medium between the MCU function test device and the MCU, and the information transmission between the MCU function test device and the MCU can be realized through the auxiliary test unit. The communication service may be established through an adb command.
Firstly, step S1 is executed, and communication connection between the MCU function testing device and the MCU is established based on communication service between the MCU function testing device and the auxiliary testing unit. The auxiliary test unit is in communication connection with the MCU function test device and the MCU, so that the MCU function test device and the MCU are also in communication connection.
It should be noted that the communication protocol between the auxiliary test unit and the MCU is the same as the communication protocol between the MCU and the SOC, and is a target communication protocol. Therefore, the communication function test between the MCU and the SOC can be realized while the MCU function test is realized, so that the MCU qualified through the MCU function test method can meet the actual requirement and can be matched with the SOC.
The target communication protocol may be one of a Universal Asynchronous Receiver/Transmitter (UART) communication protocol, a Serial Peripheral Interface (SPI) communication protocol, an Inter-Integrated Circuit (IIC) communication protocol, and a Controller Area Network (CAN) communication protocol.
And then, executing the test case script corresponding to the to-be-tested function of the micro control unit. The function to be tested refers to a function which needs to be tested whether the micro control unit is normal or not, and may include, for example, a volume adjusting function, a sound effect adjusting function, a sound adjusting function and the like of a sound module, a vehicle body control function, a vehicle control function and the like of a vehicle body vehicle control module, a power management function of a power management module, a GPIO signal detection function of a GPIO signal detection module, a DSP control function of a DSP control module and the like.
Each function to be tested of the MCU is provided with a corresponding test case script which is compiled by research personnel in advance and used for executing the test of the function to be tested. For example, if the function to be tested is a volume adjustment function and the corresponding function module is a sound module, the test case script is used to verify the volume adjustment function of the sound module of the MCU, and verify an effective channel value, an invalid channel, an invalid volume, an effective volume, or an abnormal scene, such as volume adjustment in a silent mode, respectively.
And when the test case script is executed, calling the function module script corresponding to the function to be tested through the test case script. The function module script is a script corresponding to each function module of the micro control unit, is also written by research and development personnel in advance, and is used for executing and realizing the control of the function module of the micro control unit.
For example, if the function to be tested is a volume adjustment function, the corresponding function module is a sound module, and the corresponding function module script is a sound module script (e.g., audio. For another example, if the function to be tested is a vehicle body control function, the corresponding function module is a vehicle body vehicle control module, and the corresponding function module script is a vehicle body vehicle control module script.
And then step S2 is executed, test data can be sent to the micro control unit through the functional module script, and the micro control unit executes the function to be tested according to the test data after receiving the test data. It can be understood that the test data is related data for performing a functional test included in the test case script, and may be a value of a functional parameter in the functional information of the function to be tested in the target communication protocol. For example, if the function to be tested is a volume adjustment function, the test data may include a value of a sound channel (channel), a value of a volume (volume), and the like.
And finally, executing a step S3, namely receiving an execution result corresponding to the function to be tested fed back by the micro control unit, wherein the execution result is a test result of the function to be tested.
The method for testing the functions of the micro control unit comprises the steps of firstly establishing communication connection with the micro control unit based on communication service between the micro control unit and an auxiliary test unit, and executing a test case script corresponding to a function to be tested of the micro control unit; then based on the test case script, calling a function module script corresponding to the function to be tested, and based on the function module script, sending test data to the micro control unit so that the micro control unit executes the function to be tested based on the test data; and finally, receiving an execution result fed back by the micro control unit, realizing the acquisition of a test result and finishing the test. The method has no dependence on SOC function, can expose the problem generated by MCU function in time, greatly reduces the problem analysis cost and has stronger practicability. Moreover, the method does not need manual verification, and is high in testing efficiency and low in testing cost. In addition, the method is a function test realized on the premise of the known function to be tested, and is a white box test, so that the test coverage of the MCU function is higher.
On the basis of the foregoing embodiment, in the MCU function test method provided in the embodiment of the present invention, the function module script includes an interface function of a function module corresponding to the function to be tested, and the interface function is obtained by mapping function information of the function to be tested in the target communication protocol.
Specifically, in the embodiment of the present invention, the function module script may be an interface function of a function module corresponding to the function to be tested, and the interface function may be obtained by mapping function information of the function to be tested in the target communication protocol. The function information may include a function module ID, a function ID to be tested, and a function parameter of the function to be tested, etc. For example, the function to be tested is a volume adjustment function, the corresponding function module is a sound module, and the function information of the function to be tested in the target communication protocol may include that the function module ID is 1, the function ID to be tested is 2, the function parameter 1 is a sound channel (channel), and the function parameter 2 is a volume (volume).
Further, the obtained interface function may be setVolume (channel, volume).
It can be understood that, the MCU function test device can use the interface function to implement that the function information is sent to the communication service according to the mapping table of the target communication protocol, and the communication service sends the function information to the MCU through the auxiliary test unit.
In the embodiment of the invention, the functional module script is obtained in a target communication protocol mapping mode, so that the function test result of the MCU can conform to the actual application scene of the MCU, and the control process of the functional module of the MCU can be simplified.

establishing a communication connection with the auxiliary test unit based on the communication service;
and establishing communication connection between the auxiliary test unit and the micro control unit based on a first communication process, wherein the communication protocol of the first communication process is the target communication protocol.
Specifically, in the embodiment of the present invention, when the MCU function test apparatus establishes a communication connection between itself and the MCU through a communication service between itself and the auxiliary test unit, the communication connection between itself and the auxiliary test unit may be established through a communication service between itself and the auxiliary test unit. And because the auxiliary test unit and the MCU establish communication connection based on the first communication process, the MCU function test device can automatically realize communication connection between the MCU and the auxiliary test unit. The auxiliary test unit can establish a first communication process, and then establishes communication connection with the MCU through the first communication process.
The communication protocol of the first communication process is a target communication protocol, and taking the target communication protocol as the UART communication protocol as an example, the first communication process is a UART process.

The external port corresponding to the MCU may be an external communication port in the MCU home region, and if the MCU home region is a cockpit domain, the external port corresponding to the MCU may be 7100.
When the communication service is established through the adb command, the communication service establishment command may be expressed as: adb forward tcp:6100 tcp. When the auxiliary test unit is an MCUPIPE service unit in the SOC of the cabin domain, the MCUPIPE service unit may be started through the adb command, and the MCUPIPE service unit start command may be represented as: adb shell mcupipe.
Accordingly, when the MCU function test apparatus establishes a communication connection with the auxiliary test unit according to the communication service, a second communication process may be created through the communication service, and a local port may be bound in the second communication process.
Thereafter, a communication connection with the auxiliary test unit can be established according to the second communication process and a third communication process which is created by the auxiliary test unit and is bound with the external port. Namely, after the local port is bound in the second communication process, the first data sending operation and the first data receiving operation of the MCU function testing device side between the MCU function testing device and the auxiliary testing unit can be realized. The first data transmission operation may include: the communication service analyzes the test data, encapsulates the analysis result according to a target communication protocol, and then sends the encapsulation result to the auxiliary test unit through a second communication process; the first data receiving operation may include: the communication service analyzes the data from the auxiliary test unit according to a target communication protocol, feeds an analysis result back to the MCU function test device, and displays the result through hardware equipment bearing the MCU function test device.
The auxiliary test unit may create a third communication process and bind the external port in the third communication process. After the external port is bound in the third communication process, the second data transmission operation and the second data receiving operation of the auxiliary test unit side between the MCU function test device and the auxiliary test unit can be realized. The second data transmission operation may include: receiving data sent by the MCU through a target communication protocol, packaging according to the requirement of a communication protocol corresponding to a third communication process, and sending a packaging result to the communication service of the MCU function testing device through the communication protocol corresponding to the third communication process; the second data receiving operation may include: and analyzing the data sent by the MCU function testing device, sending the data to the MCU through a target communication protocol, finishing function response by the MCU, and feeding back an execution result.
